Fluorite inclusion in topaz

One of the many interesting finds among the minerals from the Mogok area in Burma. A fragment of topaz conceals a mysterious green crystalline object, which is nothing other than an inclusion composed of fluorite. However, this mineral is not the only intruder in the topaz! At the bottom of the fragment, several rusty-brown, needle-like inclusions of the mineral columbite are clearly visible. A mineralogical gem—an aquarium inside a topaz!
